Anthony Joshua appears very relaxed ahead of the defence of his WBA and IBF heavyweight titles against Carlos Takam in Cardiff on Saturday night.Joshua is heavy favourite to beat the Cameroonian and extend his record to 20-0.And ‘AJ’ will be bigger and better after weighing his career heaviest at 18 stone and two pounds.Joshua was in fine spirits in front of the 2,000 strong sellout crowd at the Motorsport Arena in Cardiff during his weigh-in.He joked about his weight by saying: "I'd been starving myself. Maybe I'm starting to fill out as I get older and find my natural weight? Who knows what it is, but I feel fitter than I have for any fight.”And he also had time to mock his promoter, Eddie Hearn.When Joshua had the microphone, he asked everyone for a “big cheer for Eddie Hearn.”It’s fair to say Hearn splits opinion amongst boxing fans and Joshua was always asking a lot for them to give him “a big cheer.”What happened next had Joshua laughing hysterically as everyone remained silent with even a few boos.

Watch: Joshua asks for "a big cheer for Eddie Hearn"

Take a look:

Hearn certainly won’t be thanking Joshua for that…

Joshua isn't taking Takam for granted

Despite the expectations for him to win convincingly, Joshua certainly won’t be getting complacent.

"I think too much confidence can become cocky,” Joshua added.

I've got to keep a cool head on my shoulders. I didn't expect a turnout like this, I appreciate it.

"I think he's got a mindset of nothing to lose. He came in and grabbed my hand to see who's got the stronger handshake. It's a dangerous mindset.

"I have to find a way to break him down, round by round. #StayHungry. I'm hungry still, forever and ever. Everybody is hungry to succeed at whatever they are doing.

"You can be on the defensive but conserving energy. With Wladimir it was intense. Knowing my position in the ring. Being comfortable even when I'm not attacking.”
